If you have a few months in your schedule, I'd wait for the new Victor Jr coming this summer from Edelbrock. Single plane with stock height carburetor pad.

I'll be acquiring the port injection model when it becomes available and matching it up with the Edelbrock fuel rails and an Aces injection system for my 350/413 stroker.

In my opinion the Victor Jr will be too large a manifold for that engine. One of my cars with a fairly mild 455 that makes around 525 HP had a Northwind intake on it. Just on a hunch I swapped it out for a Performer RPM and the car picked up .12 in the 1/4. I think the Victor Jr and Northwind are going to be similar intakes, size wise. I think the Hurricane, Holley Street Dominator, or Torker II would be the way to go for Charley's engine

Edelbrock is saying the manifold is good for engines up to 500 cu in, but I did notice a significant difference between the carburetor version and the port injection version. The carburetor version has a power range of 3500-7500 rpm, but the port injection model is rated for 1500-7500 rpm. So I would agree it may be too much with a carburetor and the potential for poor fuel delivery at lower engine speeds.

I Was going to do that but then I was researching it and came up with the same thing that Gary said. So, I moved on from that idea. It looks like a great manifold though.

Thanks

Same height as the rpm intake..it is higher than stock.

You are correct.

While it's not a "stock height carb pad", it sure looks VERY similar to a North Wind, which is available now.

I mentioned this in the link I posted. So there is no misunderstanding, the Holley Street Dominator intake, and the testing I mention, in post #20 here was done with an intake modified by Dave Bisschop.
Again, the entrance opening was about 2.300" tall, with some runner blending and plenum work.The Edelbrock cylinder heads in use were about 313 cfm when tested on my engine builder's bench.

Also noted, Skip Fix borrowed this HSD intake from me and dynoed his 455 pump gas motor in the 78 TA with it. Tested it against his ported Torker II intake that he spent a LOT of time grinding way up the runners and using a snap gauge to check width and height. The two intakes produced almost identical dyno numbers.

I thought the Holley Street Dominator needed a lot of work to make power? What's this I've heard about welding two back halves together and doing a bunch of mumbo jumbo to make them work? Do they work with just a port clean up?

I believe that’s the original Torker that you’re referring too, many folks suggested that the runners weren’t optimized and due to the first design you’d have to weld two halves together.

Overall I think most folks agree that the HSD is good manifold without modifications but once ported by folks like Dave Bishop they really come alive.

I ran a Torker 2 in our 68 Firebird and stock hood with no issues. Was around 590 hp and 600 T. We ran a 950 quickfuel carb. If your running a Q-jet I'm thinking a different intake would be better. Wasn't the Torker 1 designed for q-jets?

Ok thanks. I really wasn't sure how that manifold will fit because the motor was pulled before he asked me for help.

Yes, I have an original Torker and it was designed for Q-Jets.

As i've posted longk ago, the Torker I can do very well with a Plenum porting(hogout) using a drill press and rasp to unshroud the runner ceilings from/to the Spreadbore openings.

Becomes a low 10 sec manifold for under 5-Lbs metal, and supports 9.0:1 Street use too.

Otherwise the 68-70's Factory iron Manifold is good enough for Street use, having the air-inhale isolation (5-7, 2-1, 4-3, 6-5) that the single-planes lack.

I hope the Speedmaster dual-plane is "all that" the Factory Iron is, with bonus being the Fuel Injection bosses.

Airhorns; itsa all true. I figure the trumpet opening is best: inlet edge is 90* from the air flow, like a musical trumpet but squat.

Torker 2 if not a proper stock intake and Qjet.

[charlie66]

It's in decent shape.

A fwiw for interest. I did some back-to-back dyno testing. The HSD intake with my HP950 carb and a 1/2" open spacer made 589.4 hp at about 5700 rpm on the dyno, this was on a previous pump gas 4.210 stroke 462cid street engine. With the same engine & carb my Victor intake with 1/2" carb spacer made 600.9 hp at 6000 rpm. Both intakes had a port entrance opening about 2.300" tall, and were properly port matched to the cylinder heads in use.

HSD / no carb spacer:
577.9 hp at 5700 rpm, 581.0 ft.lbs. at 4400 rpm.

HSD / 1/2" open spacer:
589.4 hp at 5600/5700 rpm, 589.0 ft.lbs. at 4600 rpm.

HSD/ 1" open spacer:
589.8 hp at 5700 rpm, 590.8 ft.lbs. at 4400 rpm

I know peak numbers don't express much, really need to look at the curve with each different spacer.

I went with the speed master - hurricane manifold. Port alignment was horrible. My opinion is Port match Holly Street dominator and go with that. I used it anyhow car does run real strong though.

[Steve C.]

A FWIW.....

The same situation on a Holley Street Dominator intake applies as on a Tomahawk/Hurricane intake if the ported cylinder heads have tall ports in use.

Regarding the intake gasket port height to match, you can go as tall as a SCE #128103 intake gasket without welding ( about a 2.3 tall port), BUT there is not much meat at the top with it for sealing.

The SCE catalog on page 203 states the 128103 gasket is 2.30" tall.

https://www.scegaskets.com/wp-conten...25.V3__WEB.pdf

This is not necessarly a recommendation here for that specific intake gasket. However I've used the particular gasket on all my ported cylinder heads over the years.
Every SCE128103 I have purchased and used had a actual port height opening about 2.320" tall.

Ok, Thank you. Have you ever tried a Street Dominator?
